Show HN: Bricks – One Click Dashboards from Your Data Using AI Hi HN We’ve been building Bricks to make dashboard creation as simple as dropping a file. You upload your data and Bricks does the rest: • Detects the structure • Picks the most useful charts and tables • Generates plain language insights and summaries • Applies a theme • Lets you add blocks using a natural language prompt • Exports to PDF or shares as a live link We built this because creating clean dashboards from spreadsheets felt way harder than it should be. We’d love your feedback on: • How useful the first dashboard feels • Any missing chart types or formats • Anything else that could make it better Thanks for taking a look. https://ift.tt/bK4fSl6 May 21, 2025 at 12:39AM

Show HN: Porting Mutable Instruments to Arduino, RP2040 https://ift.tt/0bDpW1d

Show HN: Porting Mutable Instruments to Arduino, RP2040 I'm sharing this since it's been eating at me since about 2021 :) A little background and example sounds at https://ift.tt/4faAPnD In short, Volker Boehm had done some ports of the MI synthesis code in 2020, unbeknownst to me. Once I discovered it a bit over a month ago and compiled his supercollider port, I realized, no excuses, get to it. The intention is to keep the source as simple to use in an arduino context, so it's NOT as nice from a c++ developers vantage point. But, I think it's becoming approachable for less adept programmers. Niek from Sluisbrinke has pushed me along, wanting to build a 'Meta-Mi' module: https://ift.tt/OHjSyXn I just play these things on my scarp. https://ift.tt/MiLuZrO May 21, 2025 at 12:09AM

Show HN: Python Simulator of David Deutsch’s "Constructor Theory of Time" https://ift.tt/W8DYCJj

Show HN: Python Simulator of David Deutsch’s "Constructor Theory of Time" Hi HN, I turned the freshly published paper “The Constructor Theory of Time” by David Deutsch and Chiara Marletto (arXiv, 13 May 2025) into an executable Python library. What you’ll find • One-to-one translation of the paper’s formalism: Substrates, Attributes, Tasks, Constructors, and task-algebra operators • Possibility / impossibility predicates and counterfactuals encoded exactly as defined • Test suite that mirrors every lemma and example (>95 % coverage, mypy-typed) • Reproductions of key results: time-keeping substrates, irreversibility proofs, quantum branching tasks, and a self-replicating constructor Why share? Reading the paper is tough going; expressing each definition in code clarified the ideas and surfaced a couple of questions for discussion. Hoping it helps others and sparks extensions. Looking for feedback: • Did I miss any subtleties in the formalism? • Which additional theorems or examples would you like implemented next? Repo: https://ift.tt/1q3cm02 Thanks for taking a look—issues and PRs welcome! https://ift.tt/1q3cm02 May 19, 2025 at 01:52AM

Show HN: Vaev – A browser engine built from scratch (It renders google.com) We’ve been working on Vaev, a minimal web browser engine built from scratch. It supports HTML/XHTML, the CSS cascade, @page rules for pagination, and print-to-PDF rendering. It even handles calc(), var(), and percentage units—and yes, it renders Google.com (mostly). This is an experimental project focused on learning and exploration. Networking is basic ( http:// and file:// only), and grid layouts aren’t supported yet, but we’re making progress fast. We’d love your thoughts and feedback. https://ift.tt/pnA3jMf May 18, 2025 at 11:24PM

Show HN: Blacklight – secret scanner for code, databases, drives, and slack https://ift.tt/hwfsyOu

Show HN: Blacklight – secret scanner for code, databases, drives, and slack We often ran pattern matching searches for secrets and keys across codebases, databases etc. Therefore, we thought about converting that workflow into a tool that we could just easily generate a SARIF report and share with our customers. Blacklight is a powerful secret, key, and sensitive data scanning tool that helps you detect and prevent sensitive information leaks in your codebase, databases, cloud storage, and communication platforms. The idea is that one can add their custom rules around their governance and compliance requirements. The platform comes with 114 matching criteria, but this can be extended easily. https://ift.tt/faA7i6j May 18, 2025 at 12:10AM

Show HN: Solidis – Tiny TS Redis client, no deps, for serverless https://ift.tt/NhGMuOz

Show HN: Solidis – Tiny TS Redis client, no deps, for serverless Hey everyone! Over the past two years I threw myself back into full-time engineering with a simple goal: write code that gives back to the community. After a lot of late-night FOMO (“AI will do it all for us, right?”) and some painful production incidents, I finally turned my weekend project into an open-source library. [ What is Solidis ? ] - Super-light (< 30 KB) RESP2/RESP3 client with zero runtime deps and first-class ESM/CJS support. - Fully tree-shakable – import only the commands you need. - Written with SOLID principles & full TypeScript typings for every command. - Designed for cold-start sensitive serverless platforms (small bundle + tiny memory footprint). [ Why I built it ] 1. node-redis & ioredis pain - ESM is still an after-thought. - Hidden deadlocks on RST, vague error surfaces. - Everything gets bundled, even commands you’ll never call. 2. I refuse to add a dependency I don’t fully understand – I literally read candidates 10× before `npm i`. 3. Serverless bills love to remind me that every KB and millisecond matters. [ Key features ] - Protocols: RESP2 and RESP3 (auto-negotiation) - Bundle size: `<30 KB` (core) / `<105 KB` (full) - Dependencies: 0 - Extensibility: Drop-in command plugins, custom transactions - Reliability: Auto-reconnect, per-command timeouts, type-checked replies [ Roadmap / Help wanted ] - Benchmarks against `node-redis` & `ioredis` (PRs welcome!) - More first-class Valkey love - Fuzz-testing the parser - Docs site – the README came first; I’d love help polishing full docs This might be my last big OSS push for a while, so stars, issues, and PRs mean the world . If Solidis saves you some cold-start time or just scratches a TypeScript itch, let me know! Repo: https://github.com/vcms-io/solidis License: MIT Thanks for reading, and happy hacking!

Show HN: Easel – Code multiplayer games like singleplayer https://ift.tt/uboGBSV

Show HN: Easel – Code multiplayer games like singleplayer For the past 3 years, I've been creating a new 2D game programming language where the multiplayer is completely automatic. The idea is that someone who doesn't even know what a "remote procedure call" is can make a multiplayer game by just setting `maxHumanPlayers=5` and it "just works". The trick is the whole game simulation, including all the concurrent threads, can be executed deterministically and snapshotted for rollback netcode. Normally when coding multiplayer you have to worry about following "the rules of multiplayer" like avoiding non-determinism, or not modifying entities your client has no authority over, but all that is just way too hard for someone who just wants to get straight into making games. So my idea was that if we put multiplayer into the fabric of the programming language, below all of your code, we can make the entire language multiplayer-safe. In Easel the entire world is hermetically sealed - there is nothing you can do to break multiplayer, which means it suits someone who just wants to make games and not learn all about networking. I've had people make multiplayer games on their first day of coding with Easel because you basically cannot go wrong. There were so many other interesting things that went into this project. It's written in Rust and compiled to WebAssembly because I think that the zero-download nature of the web is a better way of getting many people together into multiplayer games. The networking is done by relaying peer-to-peer connections through Cloudflare Calls, which means Cloudflare collates the messages and reduces the bandwidth requirements for the clients so games can have more players. I also took inspiration from my experience React when creating this language, here's how you would make a ship change color from green to red as it loses health: `with Health { ImageSprite(@ship.svg, color=(Health / MaxHealth).BlendHue(#ff6600, #66ff00)) }` There is a lot of hidden magic that makes the code snippet above work - it creates a async coroutine that loops each time Health sends a signal, and the ImageSprite has an implicit ID assigned by the compiler so it knows which one to update each time around the loop. All of this lets you work at a higher level of abstraction and, in my opinion, make code that is easier to understand. Speaking of async coroutines, my belief is that they don't get used enough in other game engines because their lifetimes are not tied to anything - you have this danger where they can outlive their entities and crash your game. In Easel each async task lives and dies with its entity, which is why we call them behaviors. Clear lifetime semantics makes it safe to use async tasks everywhere in Easel, which is why Easel games often consist of thousands of concurrently-executing behaviors. In my opinion, this untangles your code and makes it easier to understand. That's just the beginning, there is even more to talk about, it has been a long journey these past 3 years, but I will stop there for now! I hope that, even for those people who don't care about the multiplayer capabilities of Easel, they just find it an interesting proposal of how a next-generation game programming language could work. The Editor runs in your web browser and is free to play around with, so I would love to see more people try out making some games!

Show HN: AsianMOM – WebGPU Vision-LLM app that roasts you like ur mom in-browser Randomly got inspired yesterday seeing SmolVLM working on WebGPU and had the silly idea for this project. it's not perfect and super limited because of the current limitations of WebML (and admittedly, because I suck at prompting, but that's why it's Open Source haha) but it is 1.5B WORTH OF AI (SmolVLM 500M and LLama 3.2 1B) working RIGHT IN YOUR BROWSER with you not having to install anything! In fact, the whole thing is actually just an index.html that you can install and even use directly! It might be a little bit slow on first try (takes about 3 mins) when it installs models, but it caches it so it's way faster the second time (also, it's available offline after it's cached haha) Works on any modern web browser It may be a funny little project, but it's genuinely taught me so much about WebML and Vision models, and the technologies we're getting with WebML will 100% democratize AI access and make it way simpler and easier to be used everywhere :p GH Repo in case you're interested: https://ift.tt/ICPamkE https://ift.tt/DzHZnWV May 16, 2025 at 12:50AM

Show HN: Family Folder – Help your family remember everything, organise anything https://ift.tt/jVUuHAY

Show HN: Family Folder – Help your family remember everything, organise anything Hi Show HN, I’m both nervous and excited to share what I’ve been working on in the early mornings and late evenings over the past few months: Family Folder – a tool to help you and your loved ones stay connected, simplify planning, and never miss a moment. This is mostly a solo project—though I’ve leaned on ChatGPT and Upwork when I hit the limits of my technical skills. I love learning, and this has been a crash course in programming, DevOps, design, UX, and everything in between. The idea came directly from my own experience: trying to keep on top of family life, from newborns to supporting my mum’s memory, birthdays, childcare logistics, and where the insurance documents are stored. Existing tools felt too generic, too corporate, or too messy. I wanted something built for families. Stack: • Ruby on Rails 7 (via Jumpstart Pro) • PostgreSQL • Hosted on Heroku (EU region) • S3 (EU) for file uploads • (Coming soon: iOS app & AI assistant) Family Folder is private by design—you only see what you’re invited to. It’s meant to be simple enough for parents or siblings to actually use, but structured enough to avoid chaos. If this sounds useful—or if you’ve ever tried to manage a family using group chats or shared docs—I’d love your feedback. What would make something like this truly work for your family? Thanks for taking a look! – Tony https://ift.tt/Z9MoIAn https://ift.tt/Z9MoIAn May 15, 2025 at 12:27AM

Show HN: Build a free linktree alternative that skips in-app-browsers https://ift.tt/fPVZDTW

Show HN: Build a free linktree alternative that skips in-app-browsers I searched for something like this and couldn’t find it. I thought, this can’t be that hard, so I built it myself. What really messed me up was that social media apps open websites inside their in-app browsers… It costs nothing to run, so it’s free for everyone. You only need to sign up if you want to create your own link page. If you just want to convert your existing link into one that automatically skips the in-app browser, you can do that without an account. I used Next.js and MongoDB. And I’m proud to say: Not Vibe-Coded! Let me know if you need help or have questions. https://ift.tt/ODBVnk4 May 14, 2025 at 11:18PM

Show HN: Doxxer – CLI tool for dynamic SemVer versioning using tags https://ift.tt/hufrVjb

Show HN: Doxxer – CLI tool for dynamic SemVer versioning using tags Hi, first time poster here! Wanted to share a small CLI utility in Rust: doxxer! It is a tool for working with Git repositories, more specifically, extracting and calculating current/upcoming semantic versions for your repo's tags. It is heavily inspired by the output from "git describe --tags". Why use anything else then? The output is not fully SemVer compliant and therefore I was modifying it in all my projects separately, which I wanted to avoid. Single binary, single predictable output. It does not currently have pre-built binaries, so you have to install it via cargo, but it's in the roadmap! https://ift.tt/2qmGTbY May 14, 2025 at 08:40PM
